Electricity Plans in Flower Mound, TX (75028)

Rates across the Oncor territory

At 1,000 kWh/month, advertised energy rates on the Oncor utility currently range from 8.9¢ to 17.9¢ per kWh across 142 comparable fixed-rate plans.

In Texas, which retail plans you can buy and what they cost are set at the utility (TDU) level, not by ZIP code. Every address served by Oncor Electric Delivery Company sees this same plan list at these same filed prices, so Flower Mound is neither a better nor a worse deal than any other city on the same utility. What genuinely changes from place to place is how much electricity a household uses — and because plans carry base charges and usage credits at thresholds, that changes which plan costs the least.

These figures are based on Power to Choose (PTC) regulator-filed average prices at 1,000 kWh; each plan's own Electricity Facts Label (EFL) is the authoritative source for its exact rates, fees, and terms. The lowest advertised rates may apply only at specific usage levels or carry conditions, and your actual bill also depends on your utility's delivery charges. Ranges are not a promise of any specific rate or savings.

What actually differs in Flower Mound

Local weather for 75028 is what makes Flower Mound different. Across 382 days of daily NOAA climate records (2025-08-16 to 2026-09-08), the month with the most heating and cooling demand here — August 2026, a summer month — ran about 801 heating-and-cooling degree days against an average month's 437: roughly 83% more heating and cooling demand than an average month in this ZIP.

Assuming about 50% of a home's electricity responds to outdoor temperature and the rest does not, a household month like that here works out nearer 1,400 kWh than the 1,000 kWh everyone quotes. The regulator files average prices at only three usage levels — 500, 1,000 and 2,000 kWh — and of those, 1,000 kWh is still the closest to 1,400 kWh. So Flower Mound's ranking is the standard 1,000 kWh ranking: here the local answer and the industry-standard answer are the same one, and we would rather say that than manufacture a difference.

That usage figure is a modeled estimate, not a measurement of any home and not a bill estimate. The degree-day numbers are measured public NOAA data for this ZIP; the step from degree days to kWh assumes a temperature-responsive share of 50% and is anchored to the 1,000 kWh reference level, so only the shape across months comes from local weather. Your own usage depends on your home, your equipment and your habits.

Plans ordered at 1,000 kWh

So the ordering below is the ordering at the standard 1,000 kWh level — the same ordering every other city on this utility sees. What a local usage level buys you is the confidence that it is the right level for Flower Mound, not a different list.

This table IS a ranking, and it is ranked by exactly one thing: each plan's Power to Choose regulator-filed average price at 1,000 kWh, lowest first. At a fixed usage level that ordering is the same as ordering by total monthly cost. It is not a recommendation, it says nothing about any other usage level, and it ignores contract length, deposit, renewable content and early-termination terms. Each plan's Electricity Facts Label (EFL) remains the authoritative source for its exact rates, fees and terms.

Example plans on this utility

Illustrative sample, not a ranking or recommendation. The table below is a representative spread of fixed-rate plans available on the Oncor utility — chosen to span the rate distribution, not the lowest-priced plans — and listed alphabetically by provider, so the order carries no ranking. Each plan's rate is shown at the 1,000 kWh energy level; use the Fact Sheet link to read that plan's official Electricity Facts Label (EFL), the authoritative source for its exact rates, fees, and terms. The right plan depends on your household's actual monthly usage.

How comparison works

Texas has a deregulated electricity market, so most Flower Mound households can choose their retail electricity provider. The advertised per-kWh rate is only part of the story — your real cost depends on how much you use each month and on your utility's delivery charges, which are the same no matter which provider you pick. The free comparison tool projects each plan's cost against your own 12-month usage pattern so you can compare on what you'd actually pay.

How to think about this

• How plan costs change at 500, 1,000 and 2,000 kWh — why the plan that wins at one usage level loses at another.
• Comparing plans against your actual 12-month usage — how to compare on what you would really pay.
• How switching electricity providers works in Texas — what happens after you pick a plan.
• Free-nights plans versus plain fixed rate — a plan shape whose value depends entirely on when you use power.
